To all whom t 71mg concern..-

Be'it known that I, WILLIAM Pancras, of. tlleclty of Baltimore, in the State of Maryland, have invented certain non7 and useful Improvements in Bottleiealing Devices; and I dohereby declarethat the" follcwing'specication, taken in connection .with -the drawings furnished and forming a partei the saine,

is a clear, true, and completo description of my invention. v p

Thann vements to ce hereinafter speciin connection with metallic sealing-caps embodyingcertain novel featn res,which,hroadi y considered, will constitute in part the subject ot a separate application *for Letters Patent.

(See Serial No. 355,603.)

My said sealing; caps have" corrugated anges,and they are'employed with sea-lingdisks, and the flanges are heut into locking contact with bottle-heads, all as fully/set forth and claimed in my said other applicatiomhnt the particular caps hereinafter described are n l, provided with.l loops for enabling them to he .2

conveniently removed from a hott-lc hy means of any form of lever capable of into or through a loop.

This application further relates te a novel sealing-disk capable of and. well adapted to use with any form of sealing-cap, because oi' its effective and reliable sealing capacity and its odorless and tasteless character, .and also because of its low cost as compared with disks i composed of rubber com pounds or of corlr in sealing-disk properly applied thereto. y is a sectional view of the bottle, theoap, and' thosalin'gzdisk on a 'scale somewhat larger V5c y i rillustratemy sealing-caps `provided with f urits natural condition.

After describing the several features oi in vcntion, each will beispecied in appropriate clauses of claim hereunto annexed.

Referring to the drawings, Figures l, 2, and -3 illustrate one of my sealing-caps in top View, side view, and'central section. Figg, 4, in top and edge views, illustrates the form. of sealingdisk best suited for use with my sealing-caps.' 'Fig-.5 is aside view of a bottle-head 'adapted for use with my sealing-cap. Fig. 6 isa similar view of a bottle-head with the cap and its Fig. 7

than inthe preceding figures. Figs. 8 and 9 ther 'specalmeans for. facilitating their remoral from bottles, the saine consisting of different kinds of loops, and these caps also' have their lower edges flared or flattened. Figs. 10 and l1 illustrate diierent forms of packing or scaling' disks with which my sealing-caps maybe successfully used. Fig". l2 illustrates a tool devised for use asa handlever for wrenching the scaling-caps from botties. Fig. i3 illustrates my sealing-cap in a less desirable form, its pendent flange being slotted instead olcontinuous, as in the preceding figures.

ln each instance, A denotes a sheet-metal sealingcap embodying my present invention. The said cap has a iiat top @fand an integral continuous corrugated flange o. The corrugations are parallel with the axis of the cap and extend substantially throughout the depth ci the flange, and for the purposes of this speeiiication lwill designate the'outer l portion ci each corrugation an outer corrugation Il and the alternating portion an inner corrugation b2. y.

inasmuch as some cushioning or packing medium must he employed in connection with all metallic sealingcaps, I will nomwithoul.

bottle, having as an essential feature an a`nj Above this shoulder e' the nular shoulder .1'. bottleliead is inwardly beveled, as shown, to the lip of the bottle, and below the head is rounded out or headed; but these portions vided that the engaging character of the shoulder c is not thereby adversely affected. When the top of the cap has been properly forced upon the sealing inediu'in,the pendent Y of the head may be indefinitely varied, pro-V 9'.

.flange should so overlie the shoulder that the' latter may be properly embraced by the ini ner corrugations if.

As sho-wn in Fig. the sealingdisk C, al

though normally fiat, has been made toprop-` f orly lconform to the lip of the bottle by heavy pressure applied to the top of the-cap, the bottle being,r ot' course lirmly supported atvits base, and while this vertical pressure is being maintained a settingdie,wl1icl1 is ring-shaped in form and has a proper internal die" (er,

roo

isfcrccd downward upon and around the flange, and by Aforcibly engaging with the.

outer 'corrngations b it slightly a'tt'ens them, as at b, Vfor .a portion of .their length; but nevertheless their sides are suiiici'ently rigid 5 to cause a portion of each inner corrugatidu b2 to be so bent, as at b4,.that it accuratelyof thefbcttle as was secured by tlie pressure applied to the cap prior to the circuniferem' tial compression of .the corrugated flange.V The best results will accrue with a liange'ek;v

tended sofar beloiw" -the engagingshdulder that a portion of each inner corrugation-remains subst-antiaily intact; but fair results' can be'obtained even if the extreme lower inwardly and made to conform ro the engagin,eg-shoulder.V 'i

My sealing-cap thus-constructedfandlh plied is capable of successfully resisting any need ever be subjected, and `ittollows that *tfery considerable forcemust be exerted to; elect the displacement of a cap in openinga bottle, and l find that a wrenching or prying action at the top of the cap is specially effcctive.

In Figs. 1, 2, and 3 a loop d is shown to be integrally formed from the `metal of the cap top, portions thereof being cut and folded under the central' portion, which forms a. bar or loop, and the sides of the latter are slightly upturncd to enable apointed or chisel-shaped tool or hand-lever (like that shown in Fig. 12, for instance) to be'inore readily inserted beV neath theloop. In Fig. S'a loop d is composed of wire, its ends, being-inserted in appropriate small holes in the top of the cap.

Caps having applied loops, as in Fig. 8, and embodying the .described feature of my top of the cap is specially valuable in -vievr of the great strengthjrequired, coupled with the economy involved'in the production of.

such caps as distinguished from tbeuse of a non-integral loop.

My caps are so firmly united to the bottles and the force requisite for displacing them is so'great that in prying them oit the lips of the bott-les wouid be shattered and the bottles ruined by the opening-tool .were `it npt for the fact'that each sealing-disk, in addition to itsfnsnal function, new for the first time lserves as acushioned protectorffcr the lip `of The"bottle during the opening operation.

portions of said inner corrugations heifer-cedinternal pressure to which bottled liquidsl invention, will be made the subject of` a sepa-l \Vit.l1 b'eador annular rounded projec# f, it isrsoinetiines desirable that lthe interior corrugatons ot the cap-flange be initially ilaredoutvrardly at the lower edge, so that it may lloosely conformto orwithfthe coincident surface .of the beadand lthus avoid the lifting tendencywhich would be liable if the edge ot 'the gian ge vwas in forcible contact with I `theupper'snrface of the bead.v The cap of `Fig. 8 illustrates ,the inner corrugations Hattenedat theirlcwer ends, and that in Fig; 9

illustrates 'the lattening of both' the inner kfand outer corrugations at .the vedge of the f iauge, thus teri'cd .to.'

` Referring novir `to the normallyf-lat sealing'- preducing the aing edect re- "difs'k-C "of Fi-gs. 4 and '7, it is-to be understood,

wht-lettre-form there shown is deemed preferable 'byme to any other,` that the form may be varledwithout departure from inyinvention*I as, for instance-the packing medium may bea molded disk with' a projection on its under side to occupy and till theimo'uthof the bottle 1to1' securing greater area of contact with the botteas shown in Fig. 1l, or it maybeashoit cork with speciallyaring sides, as .shown in i Fig. 10, it being obvious that my sealing-cap i will'perform its proper functions in connec tion with a sealing medium of any form, if

the lattephave a suitable packing capacity.

As hereiubefore indicated, a normally-fiat sealing-disk is best suitedfOr. usewith my sealingcaps and the same would be true of anyforrnvof sealing-cap which is capable of maintaining a disk under the high degree 0f compression essential for securing propersealing clects. So far as iny knowledge extends, all prior ,sealing-disks ot practical value have either `been cut from corklwood or cut from.

sheeted vulcanized-rubber colnpound, or said lcompound has been molded into form. Ind

iirst,a close selection from the best and most I I of that reliable disks cut from cork-wood involve,

expensive grades -of cork, and, secondly, a.

close inspection' of each disk cut therefrom, because the presence of pits or cells in 'athin disk ot ccrl-Woodwill defeat the prime ob,` jects sought in bottling.

The rejected'cork-v wood disks -are practically.Wastedfiand their'.

proportion to 'the good ones is so great as to 'render the use'of cork disks impracticable in ordinary bottling operations. 'lfhe considerizo' able cost ot rubber disks is also a matter of much consequence; but while that does not preclude their extensive use they are well known to be objectionable, becausetheirsulf phurous odoris liable to iinpairliquids of delicate iiavor. I have after much experiment de- '.vised a normally-flat disk which has the dei Vsi'red resiliencygas in cork-wood or rubl'l'erlis4 practically free from objectionable odor,"s'

free from pits or cells, audwhich is more eco-i,` nomically produced than any otherA type of effective sealing-disks known'to mc. I,1':i1t my novel disks from sheets of a. complcxfab-yric composed of a textile-fabric foundation and granulated cork united in mass by a bind,y ing or adhesive medium which is practically 44odorless and tasteless-as, for instance, the refined gum derivedfroin linseed `oilwone form of such sheeted material being the best quality of linolenirn a fabric readily obtainable in open market. rl`he te'xtilefabric foundation aiords desirable strength to the disk; but for securing still greater strength they are coated ontheir inner sides with thincloth preterably charged with refined paralline, which lis Well known to be odorless and practically insoluble in such bottled liquids as will 'usually involve the useiot my sealing-caps.

`lt is oftentimes desirable, after opening a bottle and partially emptying it, to temporarily yclose it again, andjthis can be readily "done by replacing the"cap and striking it with the hand, whereby air will not only be excluded, but the cap will successfully resist any gaseous pressure which is liable t be developed Within an opened bottle of wine or beer.

My sealing-caps possess much practical value for use in connection with long corks, which might not, as a rule, be displaced by ,gaseous pressureafter the removal of the will be made the subject of a separate application for Letters Patent.

Having thus described my invention, I

vided with au integral loop at its top for fa and desire to secure by Letters fhereirbefore described, containing a sealingvdisk and composed of sheet metaLhavmg au 5o integral pendent flange-adapted to be secured lupon the head of a bottle by bending portions of the flange into locking contact with an engaging shoulder on said head and procilitating the removal of the cap from a bottle, said disk protecting the lip of the bottle from fracture While prying oit the cap.

2. A bottle-sealing cap composed of sheet metal, having a continuous integral pendent 6o' Bange corrugated substantially throughout its depth Ain lines parallel with the axis of the cap and provided with a loop for enabling the cap to be readily Wrenched from abottle V to which it has been applied;y i 65 3. A sealing-disk composedv of granulatedv cork and the practically' tasteless and odore.` less gum derived from linseed-oil, said disk being adapted for use with sealing-caps` substantially as described. y

4. A bottle-sealing cap composed of metalA and haringan integral pendent ange by which the cap may be locked to a bottle and provided at its top with an integral loop, substantially as described. j

5. A bottle-sealing cap having a flange corrugated in line with the axis of the cap and `"slitted at intervals, the corrugated portion of l the iiange being adapted to be bent into locking contact with an annular shoulder on a bottle-head, substantially as described.
